Recent successes in malaria control have been largely attributable to the deployment of insecticide - based vector control tools such as bed nets and indoor residual spraying.

He has particular interests in (1) the use of ancient DNA methods to document changes in genetic variation through time and phylogenetic relationships of extinct or endangered organisms (especially of the recently extinct Hawaiian avifauna); (2) the use of highly variable genetic markers to measure genetic structure and relatedness, and to ascertain mating systems, in natural populations, and (3) the use of genetics to study the evolutionary interactions between hosts, vectors and infectious disease organisms (e.g., major projects on introduced avian malaria in native Hawaiian birds and invasive chytrid fungus in amphibians).
